A novel technique to recover metallic Fe droplets from Ti bearing blast furnace slag and, at the same time, to enrich titanium compounds into the perovskite phase by oxidising the slag using injected air with or without injected steel slag additive, was studied and developed. The oxidation treatment enabled >85% of iron droplets in the Ti bearing slag to be agglomerated separated and the dispersed Ti components were selectively enriched into the perovskite phase from 48 to ∼95%, so enhancing subsequent separation and recovery.
